LCM of:

Least Common Multiple of 15/138,79/414

Given numbers are 15/138,79/414

Formula to find LCM of Fractions is

LCM = LCM of Numerators/GCF of Denominators

As per the formula LCM of Fractions let’s split into two parts and find the LCM of Numerators and GCF of Denominators

In the given fractions LCM of Numerators means LCM of 15,79

Least Common Multiple of Numerators i.e. LCM of 15,79 is 1185.

GCF of Denominators means GCF of 138,414 as per the given fractions.

GCF of 138,414 is 138 as it is the largest common factor for these numbers.

Lets's calculate LCM of 15,79

LCM of Fractions 15/138,79/414 is 1185/138

Given numbers has no common factors except 1. So, there LCM is their product i.e 1185

Least Common Multiple of 15,79 with GCF Formula

Least Common Multiple of 15,79 with GCF Formula

The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).

We need to calculate greatest common factor of 15,79 and common factors if more than two numbers have common factor, than apply into the LCM equation.

GCF(15,79) = 1

common factors(in case of two or more numbers have common factors) = 1

GCF(15,79) x common factors =1 x 1 = 1

LCM(15,79) = ( 15 × 79 ) / 1

LCM(15,79) = 1185 / 1

LCM(15,79) = 1185


Lets's calculate GCF of 138,414

2 138, 414
3 69, 207
23 23, 69
1, 3

∴ So the GCF of the given numbers is 2 x 3 x 23 = 138

Thus LCM of Fractions = LCM of Numerators/GCF of Denominators = 1185/138

Therefore the LCM of Fractions 15/138,79/414 is 1185/138
